CONCRETE INSERT.

Applicationiled April 27, 1920, Serial No. 377,035. Renewedvlltay` 21, 1923.

'Be it knownthat I, RAYMOND l). ZENTs,

citizen of the United States, residinor at Omaha, in the county of Douglas and tate of Nebraska., have invented certain new and usefnl Improvements in Concretelnserts, of

which the following is a specification, reference being had therein to the accompanying drawing. y

My invention relates to concrete inserts and has for its principal object a device of` simple construction `which may be inserted ink and securely held in the concrete for supportingpiping, shafting, and the like. r

rAnother object resides in constructing the e insert in such a manner that a lstrap may be secured thereto and engage overa reinforce ing rod embedded in the concrete.

A `further object consistsk in providing means for temporarily attaching t-he insert y to the form board.

:the following specification and drawings,

in which- F 1 is a front elevation rshowing the` insert with one form of attaching strap;

Fig. 2 a top plan of the insert; Fig. 3 is a bottom plan ofthe insert;

Fig. 4 is a longitudinal vertical sectiony through the insert;

F ig. 5 is ak front elevation showing another embodiment of the attaching strap;

Fig. 6 is aside elevation showing the further embodiment of the attaching strap, and

Fig. 7 is a front elevation. of still another'` embodiment of the attaching strap.

. boardr upon which the concrete .2 is adapted to be poured. My insert is indica-ted at 3 and is exteriorly tapered so that the top is of greater size than the bottom and the front face is preferably rounded. By tapering the insert the concrete will set therearound and securely hold the insert in position. A threaded socket 4: is formed in the bottom of the insert and a transversely extending slot 5 is formed from one side, above the socket, and terminates a short distance from the opposite side. A vertical opening 6 is formed from the top of the insert and leads to the socket 4 as more clearly illustrated in Fig. 4 of the drawings.

A nail 7 is adapted to be passed through thenopening 6, extends through the lsocket ,47,

and enters the form board. This nail 7 is i used for temporarily attaching the insert to the form board prior to thefpouring of the4 concrete. r y

A` perforated flexible strap `8 is inserted through the slot `5. and will be held between the closed end `of the slot and the nail 7. The

r strap is adapted to be bent and embedded in the concrete, and in the preferred embodiment of my invention the endsof thestrap will be bent around a reinforcing` rod em-iV l i bedded in the concrete. i

In Fig. l of the dra-Wings, Ihaveillus-V trated two reinforcing r0ds9 arranged nar-v allel and the ends of the perforatedlstrap. 8 are bent around these rods and extend down-` wardly in a vertical position as shown at 10.y

In F ig. 5 I have illustrated only asingle reinforcing rod `lland the ends of the strap 8 are bent over the rod .in opposite `directions to form the diagonally extending ends 12 in opposite directions. InV Fig. 6 Iv have also; illustrated a singlerod 13 and the strap, 8 is bent to form an angular extension 14 the end.

of which is bent over the'rod 113 and down-l v wardly to form an extension 15 extending parallel with the extension 141.

In that form ofA the inventionillustrated in Fig.7, I do away entirelyy with the use of the reinforcing rods. lIn this `form'of the 'invention thestrap 8 is bent so that one end forms a'semi-circularextension land the opposite end 4is bent around this semi-circular extension as indicated atv 17 and the end thereof extendsl horizontally as indicated at 18.

thought that the mode of usingmy insert, as well as the advantages, will `be clearlynnder- Fromthe above detailed description it stood. The insert is adapted to lbe embedded j ,l

in the concrete.andpipingorshafting con,- nected thereto. The insert is initially placed upon the form board l` and jtemporarilyheld in position by means of the nail 7 which extends through the vertical opening, 6, the socket 4, and engages in the form board.

`The strap 8 is extended through the slot 5 in such a position that it will engage the closed end of the slot and will be held in this position by the nail 7. If the reinforcin rods are to be used, they are placed an held in proper position and the ends of the strap 8 bent therearound. When this has been done, the concrete is poured upon the form board and will be allowed to set. After setting, the formboard is lremovedsand the nail 7 will be clipped or cut atthe top of the socket 4. By having the strap 8 perforated the concrete will pass through the perforations and more securely hold the strap and insert in position. The sides'of the insert being inclined Will allow the concrete to set around the insert vin such a `manner that the taper or incline will 'y support said insert in the concrete.v The strap 8 and the reinforcing rod form' an additional sup` port for lthe insert and atl thesarne'time the 'v strap will also aid' in the reinforcing of the concrete. o

As` shown -in- Fig. Tof the drawings, it is not vabsolutely necessary to bend the ends of the strap around the reinforcing rods, and

' the ends of said strap may be merely bent as verselyv extendingy slot terminating "ata point beyond the opening in the top." I
